.SH DESCRIPTION
These functions generate a read of various sizes from the mapped memory or
device register.
.sp
.LP
The \fBcsx_Get8()\fR, \fBcsx_Get16()\fR, \fBcsx_Get32()\fR, and
\fBcsx_Get64()\fR functions read 8 bits, 16 bits, 32 bits, and 64 bits of data,
respectively, from the device address represented by the handle, \fIhandle\fR,
at an offset in bytes represented by the offset, \fIoffset\fR.
.sp
.LP
Data that consists of more than one byte will automatically be translated to
maintain a consistent view between the host and the device based on the encoded
information in the data access handle. The translation may involve byte
swapping if the host and the device have incompatible endian characteristics.
.SH RETURN VALUES
These functions return the value read from the mapped address.
.SH CONTEXT
These functions may be called from user, kernel, or interrupt context.
